QUANTSIDE Group

Our group focuses on the study of low-dimensional quantum systems and the actual research lines are:

• Quantum transport in hybrid nanostructures;
• Quantum pumps;
• Anomalous Josephson effect;
• Topological phenomena in one and 2D materials (insulators and superconductors);
• Non-equilibrium dynamics at low-dimensions;
• Many-body effects in one-dimension and Luttinger liquids.

Low dimensional systems, in which spatial dimensions are small enough to restrict the quantum mechanical wavefunction of electrons or atoms, exhibit some of the most diverse and intriguing phenomena seen in condensed matter physics. There has been tremendous interest in low-dimensional quantum systems during the last twenty years, fueled by a constant stream of striking discoveries, the realization of new state-of-art electronic nanodevices and the potential applications in quantum technologies. Our group has concentrated its theoretical activity on the paradigm of low-dimensional systems, where “nanostructures” (based on superconductors or novel materials) can be engineered at the atomic scale. In addition, we have devoted our studies on low-dimensional systems of interest for quantum simulations, such as ultracold atomic gases loaded in anisotropic traps and optical lattices. Other low-dimensional materials that have received considerable interest, since their discovery less than a decade ago, and for which our research has contributed, are graphene and topological materials. The group's theoretical work also concerns the study of Josephson anomalous effects in peculiar superconducting systems involving, for instance, semiconductive nanowires or interfaces between complex insulating oxides. Many of the subjects covered by our group are central to the currently fashionable fields of mesoscopic and topological physics, spintronics, atomtronics, and quantum simulation.
